Under Giorno's deliberate lure, Fugo and Narancia had long since chased him to the outskirts of the fire.
And in order to kill Giorno, Fugo would definitely have Purple Haze run ahead of him.
Thus, starting from the center of the fire, then Fugo, then Purple Haze, and finally Giorno, the four had formed a line stretching from west to east.
Unfortunately—
According to the principles of thermal convection, the immense heat produced by a fire continuously caused the surrounding hot air to rise, creating a massive chimney effect.
At the same time, the rising airflow around the fire gradually produced powerful inward gusts along the ground, supplying it with additional air.
This "inward gust" was naturally a wind blowing from the outside in, from all directions toward the center of the blaze.
And from where Fugo and the others stood, this wind generated by the fire became an east wind blowing westward—from Giorno to Purple Haze, then from Purple Haze to Fugo himself.
More importantly—
The burning fire also drew in the surrounding air, greatly accelerating the airflow.
In other words, not only would the wind suddenly turn into an east wind, but this east wind stirred up by the sudden blaze would also be extremely powerful.
